hi. i had that with stimulant Rx for the add. sometimes, wellbutrin just isn't for some people. you might could do with a lower starting dose. also...prozac stays in the system a long time (long half life). my 1st thought was/is that the prozac might be making the wellbutrin blood levels higher than you'd expect from a low dose...and since you're just now starting, it could be like getting hit with 200mgs or however much, and that might be a bit much for your body to deal with. just a thought.
